Final answer:
The resources found in Southern Europe include olives and grapes, cultivated for olive oil and wine respectively, and fish from the surrounding seas. Zinc is found in Europe but is not as synonymous with Southern Europe as the other resources.
Step-by-step explanation:
The resources found in Southern Europe include a variety of natural commodities valuable to the region's economy and lifestyle. The correct answers to the resources found in Southern Europe are: a) Olives, which are cultivated extensively and used for producing olive oil; c) Grapes, which are central to the wine industry; and d) Fish, owing to access to numerous seas and oceans that provide a significant portion of the world's fish catches. While b) Zinc is also found in Europe, it is not particularly associated with Southern Europe and thus is not a top answer for that specific region.
Historically, the cultivation of olives and grapes in Greece was immensely profitable and sustained long-distance seagoing trade. Being surrounded by water bodies, Southern Europe also benefits from rich fishing grounds, though overfishing has become a concern in recent years. Zinc is a natural resource found in Europe, but it is not as strongly associated with Southern Europe as olives, grapes, and fish are.
